The main components of the EconAqua system comprise: EconAqua deflector and piping, the EconAqua valve set and water supply to the EconAqua system.

EconAqua head
The EconAqua spray nozzle consists of a deflector, fusible link or bulb, plug and the EconAqua sprinkler head frame. If the temperature rises by more than 30°C relative to the normal ambient temperature, the fusible link or bulb in the EconAqua sprinkler head trips thus allowing the water spray to eject the plug. The water spray is dispersed through the deflector on the EconAqua sprinkler head creating a spray of water mist.

EconAqua valve set
The main purpose of the EconAqua valve set is to signalise the activation of the EconAqua system. The main classification of EconAqua valve sets is the following:

EconAqua wet station is a valve set with water contained in the top and bottom chambers. Due to pressure imbalance in the top and bottom chambers (develops when the spray nozzle is set off), the plug of the EconAqua valve is elevated thus releasing the water into the alarm gong line. This line houses a pressure switch which transmits the fire alarm signal to the fire alarm control unit.

EconAqua dry station is a valve set with air contained in the top chamber and water in the bottom chamber. Due to pressure imbalance in the top and bottom chambers (occurs when the EconAqua spray nozzle is set off), the plug of the EconAqua valve is elevated thus releasing the water into the alarm gong line. This line houses an alarm gong which provides an audible notification of the fire, as well as the pressure switch which transmits the fire alarm signal to the fire alarm control unit.

Pre-action EconAqua station is a valve set with contained air in the top chamber and water in the bottom chamber. When the fire alarm system is set off and the pressure in the line drops, the electromagnetic valve is activated causing pressure imbalance to the EconAqua pre-action valve, raising the EconAqua valve plug which releases the water into the alarm gong line. This line houses an alarm gong providing an audible notification of the fire, as well as a pressure switch which transmits the fire alarm signal to the fire alarm control unit.

EconAqua system water supply
Supply of water to the EconAqua system and the shutdown time of the EconAqua system depend on the type of protected zone, type of protected material and size of the EconAqua set.

Water supply to the EconAqua system should cater to the most demanding case of fire in a building by delivering adequate pressure and adequate quantity resulting from hydraulic calculation.
